[Bug] Crash when mirroring one screen to another

[herrdiener]

Trying to mirror my laptop screen to any external monitor via HDMI on Alpha 4 crashes Cosmic with the following error:

thread 'main' panicked at 'Callback creating object zwlr_output_configuration_head_v1@9[39] did not provide any object data.': /build/cosmic-comp-SKtFZZ/cosmic-comp-0.1~1733758395~24.04~9b50d0f/vendor/wayland-backend/src/rs/server_impl/common_poll.rs:288

Extending the desktop to another screen works perfectly, the crash happens only upon choosing the mirroring option in the screen settings.
